A combined-cycle power plant comprises a gas turbine engine for generating exhaust gas, an electric generator driven by the gas turbine engine, a steam generator receiving the exhaust gas to heat water and generate steam, and a duct burner system configured to heat exhaust gas in the steam generator before generating the steam and that comprises a source of hydrogen fuel, a fuel distribution manifold to distribute the hydrogen fuel in a duct of the steam generator, and an igniter to initiate combustion of the hydrogen fuel in the exhaust gas. A method for heating exhaust gas in a steam generator for a combined-cycle power plant comprises directing combustion gas of a gas turbine engine into a duct, introducing hydrogen fuel into the duct, combusting the hydrogen fuel and the combustion gas to generate heated gas, and heating water in the duct with the heated gas to generate steam.
A duct burner system for a combined-cycle power plant comprising a gas turbine engine configured to generate exhaust gas and a steam generator configured to receive the exhaust gas from the gas turbine to heat water and generate steam, the duct burner system comprising:
A method for heating exhaust gas in a heat recovery steam generator for use in a combined-cycle power plant, the method comprising:
